Analysis of the ψ(3770) resonance in line with unitarity and analyticity constraints
We study the inclusive and exclusive cross sections of e + e - → hadrons for center-of-mass energies between 3.70 and 3.83 GeV to infer the mass, width, and couplings of the ψ ( 3770 ) resonance. By using a coupled-channel K -matrix approach, we setup our analysis to respect unitarity and the analyt...
